The new Life Event option on the social network is called 'Expecting a Baby' and will allow users to share the arrival date for any future offspring with their Facebook friends.As well as being able to add a due date, a number of other pieces of information can be included as well.These include who the other parent is, a location and a story about the pregnancy should the user so wish.There is even a tab available to include a photograph, meaning that parents can upload images of ultrasounds and pregnant stomachs prior to the birth and images of the newborn.In a blog post announcing the update, Facebook said: 'Life Events are easy and expressive ways to mark significant moments in your life such as getting married, buying a house or travelling to new places.'If you choose to, you can now share that you are expecting a baby with your friends on Facebook.'News about friends expecting babies can be found in the Celebrations area of the site's home page, above birthdays and events.
